PDW Malfunction and Limitations

PDW malfunction and sensor obscured

When PDW or a related component malfunctions, a warning message or warning light appears on the instrument cluster. When the detecting sensors are obscured, the system may be temporarily limited or disabled. The system operates properly when foreign material is removed from the sensors. If the system does not operate properly after it is removed, have your vehicle inspected by an authorized HYUNDAI dealer.

For more information, refer to Driver Assistance System Warnings and Indicators.

Detecting sensors

PDW uses the following sensors:

  • Front ultrasonic sensors

  • Front side ultrasonic sensors (if equipped)

  • Rear ultrasonic sensors

  • Rear side ultrasonic sensors (if equipped)

For more information, refer to Sensor Information.

PDW limitations

When the detecting sensors cannot detect the surrounding situations, PDW may not operate properly.

PDW may malfunction when:

  • Heavy rain or water spray is present

  • Affected by another vehicle's sensors

  • Driving on uneven road, gravel roads or bushes

  • License plate is installed in a different spot from the original location

  • An unofficial license plate is installed

  • The vehicle bumper height or ultrasonic sensor installation has been modified

  • Attaching equipment or accessories next to the ultrasonic sensors

  • A trailer or carrier is installed on the rear of your vehicle

The following objects may not be detected:

  • Sharp or slim objects, such as ropes, chains or small poles

  • Narrow objects, such as corners of a square column

  • Objects smaller than 40 in. (100 cm) in length and narrower than 6 in. (14 cm) in diameter

  • Objects, which tend to absorb sensor frequency, such as clothes, spongy material, or snow

  • Pedestrians, animals or objects that are very close to the ultrasonic sensors

  • An object in the side space between the front corner ultrasonic sensor and the rear corner ultrasonic sensor or an object approaching the side space

  • PDW is a supplemental function. The operation of PDW can be affected by several factors (including environmental conditions). It is the responsibility of the driver to always check the front and rear views before and while parking.

  • Your new vehicle warranty does not cover any accidents or damage to the vehicle due to the malfunction of PDW.

  • Pay close attention when driving near objects, pedestrians, and especially children. Some objects may not be detected by the ultrasonic sensors, due to the object's distance, size or material, all of which can limit the effectiveness of the sensor.

  • PDW may not warn you in the order of detection. It varies depending on the speed of the vehicle or the shape of a person, animal, or object.

  • If the PDW does not operate properly, have your vehicle inspected by an authorized HYUNDAI dealer.

  • Driving with the liftgate open is abnormal. For your safety, be aware and drive safely.
